X-Men: Life Science

Several organisms, such as axolotls, planarian flatworms, and starfish, possess remarkable regenerative abilities. These biological processes allow them to regrow lost limbs or damaged tissues.

Reinforcing a skeleton with a metal alloy like Adamantium involves materials science and structural design, which fall under the field of engineering. It is not related to plant life, rocks, or space.

The human skeleton provides structure, protects organs, and produces blood cells in the bone marrow. Digestion is a function of the digestive system, not the skeletal system.

Genetic mutations are natural occurrences that can happen in any human, not just those with fictional mutant powers. These mutations can be inherited or acquired throughout a person's life.

Genetics research involves studying DNA, genes, and molecular processes, which is a core component of biochemistry. It bridges the gap between biology and chemistry.

Permanent changes to an organism's traits caused by internal biological factors are typically the result of genetic mutations. These mutations alter the DNA sequence, leading to new or changed characteristics.

Humans have 46 chromosomes in total, which are organized into 23 pairs. One set of 23 comes from each parent.
